Holly Problem
I live in the John Innes conservation area - a Garden suburb the building of
which made John Innes his fortune before he founded the John Innes Institute in his country (sic, this is sw19 and was country at the turn of the century) house which now houses a school. The institute long since departed for the more rural climes of East Anglia. One imaginative thing he did was to plant all front hedges in the area with Holly, and the local park with 40 plus varieties of holly Well, so much for preamble. We have recently noticed a problem with a good number of the hollies in my street - they appear to be dying. Honey fungus is the main suspect but I'm not so sure. Most mature shrubs/trees I have seen succumb to HF seem to die off rapidly and in one go. In this case the hedges are defoliating from the ground up but the rest of the plant looks still healthy. In fact the leaf I am looking at as I type looks like someone has drawn a wavy line through one side - the right bit is dead, brown and brittle the rest of the leaf looks bright glossy and very healthy - that is typical of the leaves on all the dying hedges. I've explored the trunks of a number of trees at ground level and can see no sign at all of the characteristic white mycelium below the bark. Also, when I have seen honey Fungus go through a garden you can almost see the wavefront moving across the ground, in this case just odd plants separated by many feet are dying The local conservation group is consulting Wisley and a specialist Holly nursery, but I wondered if the collective wisdom of URG can suggest any other possibility?

This refers to the Holly Leaf Miner and Holly blight which match some of your symptoms. http://www.treeadviceservice.org.uk/pages/TAShot73.html |

"The problem can be a particularly stricking sight in hedges - as infections spread, arches of bare defoliated stems, in the shape of an inverted"v" become visible." Is an exact description of our problem! Ain't URG wonderful! pk |
